Question about Sony KP-57HW40 57" Rear Projection Television

1 Answer

Sony Color Rear Video Projector - KP 57hw40 / Mfg. February 2002

My television has progressively gotten worse over the last few months, the screen goes blue and it turns the picture off although you can still hear the sound. I am hesitant about calling a repair person becaue of the cost. Is their anything I can do to help myself? Thank you for your time and consideration.

    Thanks, I finally have had to give in and call a repair shop. To my surprise when the pick up person opened the back of his truck to load my TV it was filled with large projection TV's of every size. I guess I am not the onloy one out here with an attitude.

I have a Sony Color Rear Video Projector Model KP-57HW40. Its blue color is not working anymore and noticed some burn smell by the set which controls such blue color.


It may be the CRT drive board which is attached to the bottom of the Blue CRT. I would check that Board for signs of being burnt it may need to be replaced.
